The storm system that soaked much of the Bay Area on Thursday delivered some impressive rainfall totals to much of the region and set daily records in three cities.

It will be dry through the weekend, but the temperatures will dip into the 30s and even 20s in some places, according to the National Weather Service.

Santa Rosa (2.57 inches of rain Thursday), Oakland (1.48 inches) and San Francisco (1.31 inches) all received record amounts of rain for Dec. 15, according to the weather service.
